To rl/ZZ whom/,zit nto/,y concern.

Be it known that we, EMIL DoMsGEN and FRIEDRICH LORENZ KUJAwA, merchants, subjects of the King of Prussia, German Emperor, residing at 2 Alemannstrasse, Magdeburg, Germany, have invented a new and useful Improvement in Portable Chairs, of which the following is a specification,

Our invention refers to chairs which can be puty together compact-ly so as to occupy a very small space, in order that they may be .transported easily and unnoticeably i ,As opposed to the well -known campstools, the present invention has the advantage that it sits firmly on four legs and has reliable and substantial back and arms, which can all be put together in the form of a compact satchel-like box, which can contain articles of apparel etc. as well. i

The drawing illustrates the object of the invention in a form of construction taken by way of example, as follows:

Figures 1 4, the four sides of the chair I put together as a box or satchel from the outside, Fig. 5, the box half open, showing the legs ofthe chair lying inside. Fig. 6, the same as Fig. 5, but seen from the side, one leg having been taken out and inserted, Fig. 7 a side elevation of the chair put together for use, Fig. 8 on a larger scale than the previous, figures, a transverse section of a part, perpendicular to the view in Fig. 7. Fig. 9 also on'a larger scale, a perpendicular longitudinal section through the wood in the front part' ofthe chair.

The arrows show the directions in which the various parts move.

A box-like stand -is formed by the bottom 1, by 3 side pieces of equal width 2, and by the fourth side piece 3 which is about half as wide as the other side piecesf2. In each of the four corners of this box is a hole which goes through the bottom 1 and is continued by means of a corresponding superstructure 5 as far as possibleviz, as far as the width of the side piece 3. These holes serve to hold the legs 6 of the chair, which are put away inside the box. On the inside of each hole a spring catch is provided which slips into a groove 8 in the leg of the chair, (Fig. 8) whereby the leg is held tightly in the hole.

On the lfour superstructures 5 within the side pieces 2 is laid the frame for the seat .9, which is attached tothe front piece 3 by means of hinges 1-0, so that it can be folded over outside (Figs. 5 & 6) and one can reach into the inside of the box and remove the legs of the chair and whatever else has been placed therein. On the sides of the frame for the seat 9 the arms of the chair are attached by means of hinges 11. The supporters 12 of the arms proper 13 consist of thin pieces of wood, which are united above by the arms proper 13, so that they cannot bend out. The hinges are attached in such a way that the supporters, when they are placed perpendicular to the seat, occupy positions at the side of and beyond the frame for the seat, itting into incisions 14 in the side pieces 2, thereby rendering themselves, aswell as the seat immovable as shown in Fig. 8.' The upper edge of the frame of the seat 15,

which latter may be iliade of cane,.leather,

or similar material, lies so far below the edge of the side pieces 2 that a covering v board 16 can lie on the upper edges of the side pieces 2; this cover 16 is attached to the frame of the seat 9 by means of a bar 17, which is immovably attached to the frame for the seat; the cover 16 is attached to this bar 17 by means of hinges 18 in such a way that its under edge can rest upon the upper edge of the back. piece 2 of the box. On account of the fact that the under edge of the cover is somewhat beveled (slanted oif) the same slants backward, forming a comfortable back for the chair.

For the purpose of rendering the side pieces 2, the frame for the seat 9 and the arms 12-*13 secure, this is attached to the arm proper 13 a movable claw 19 which iits into a corresponding hook 20 in the cover, and thereby prevents the same from moving backward and forward and the arms from shutting up. Further, on the lront part of the frame for the seat a bar 21, corresponding in height to the bar 17 is attached by meansof hinges 22, by means of which when the chair is closed up, the free space caused by the arms 12-13 lying between the seat and the cover 16 is closed, 'as shown insdottedlines in Fig. S), and when the chair is set up, this bar 21 having been let down increases the length of the seat. Corresponding indentations 23 made in this bar 21 enable it to be laid easily over the hinges 1() of the seat.

In order to make a chair out of this box- IOO like apparatus, the contrivances for shutting (of any kind desired) the parts attached to each other are opened, for instance, the

locks are unlocked, or, in case hooks and:

eyes are provided'for the purpose, the same are opened. The seat andy cover are now raised, Figs. 5 6, the legs of the chair removed and inserted from outside in the holes in the bottom, and the seat and cover then put back, so that the box assumes its former closed form; the cover alone is then raised, the arms brought into position and the claws 19 attached in the hooks 2O of the cover. Ther bar 21 standing upright is turned down and the chair is ready for use.

What we claim as our invention, and desire to secure by Letters Patent, is:

1. In a portable chair the combination of a frame having one low side piece, a seat frame, hinges connecting the frame to the low side piece, a back, hinges at one edge ofthe latter, connecting the back-'f to the seat, armsand hinges attaching the arms to the seat frame, removable legs adapted to be pushed in holes of the frame and a hooking device between the said back and arms, all as described and for the purpose set forth.

2. In a portable chair the combination of an under stand having one'side piece lower than the resting three side pieces, a seat frame hinged to said lower side piece, a cover plate forming theback and hinged to the seat frame, arms hinged to the seat frame and loose legs adapted to be pushed into holes in the frame, the Whole adapted to be clasped together, to form a Satchel-like box, all as described and shown.

3. In a portable chair a frame, a bottoni plate on said frame, a superstructure in the corners of the frameA provided with holes, spring catches in the holes, 'and removable chair-legs to be inserted in the holes, a seat frame, a cover hinged on the seat frame and lying inside the frame and a cover yplate hinged to the seat and adapted to close the formed Satchel-like box.

In witness whereof we have hereunto set vour hands in presence of two witnesses.
